Abstract
A pesticidal barrier, which may be used as a liner for a building excavation to protect the building to be constructed from infestation by termites and other insect pests, takes the form of a flexible membrane. The membrane comprises an assembly of fibers or filaments. The assembly has an average void volume of less than 85% when measured under a pressure of 10 kPa (1.45 psi). The fibers in the assembly have an average fiber size of less than 6 denier. The assembly integrally incorporates within its structure, or has above or below its structure, an array or network of connected permeable-walled tubes, so that an insecticide may be delivered to all parts of the membrane, particularly after the barrier has been installed at a building site.
